We’ve installed quite a few gauge sets in the E9x M3 at this point and have created a few IND original components along the way. We took some photos of the parts we’ve built to share them with the M3Post community. We created a bolt-in oil pressure adapter that allows for an easy install of the Stack sending unit with no drilling. We also realized that the gauge wiring should be neat and tidy and pre-wire all of our gauges so that the amount of wiring is kept to a minimum and we use as many factory BMW connectors as possible.
